2-Nitrobenzoic acid Usage And Synthesis
Chemical Propertiesoff-white powder
UsesNH2-protecting reagent.
Uses2-Nitrobenzoic Acid is used as a reagent in the synthesis of several organic compounds including that of novel triazoles and a tetrazole of escitalopram which act as cholinesterase inhibitors. It is also used in the one pot synthesis of 1,4-disubstituted 1,2,3-triazoles.
DefinitionChEBI: A nitrobenzoic acid carrying the nitro substituent at position 2.
Synthesis Reference(s)The Journal of Organic Chemistry, 56, p. 5924, 1991 DOI: 10.1021/jo00020a040
Tetrahedron Letters, 35, p. 219, 1994 DOI: 10.1016/S0040-4039(00)76515-4
General DescriptionYellowish white crystals with an intensely sweet taste.
Air & Water ReactionsInsoluble in water.
Reactivity Profile2-Nitrobenzoic acid is incompatible with strong oxidizing agents. Also incompatible with strong bases. May react with cyanides .
Health HazardACUTE/CHRONIC HAZARDS: When 2-Nitrobenzoic acid is heated to decomposition it emits very toxic fumes.
Fire HazardFlash point data concerning 2-Nitrobenzoic acid are not available, however, 2-Nitrobenzoic acid is probably combustible.
Purification MethodsCrystallise the acid from *benzene (twice), n-butyl ether (twice), then water (twice). Dry and store it in a vacuum desiccator. [Le Noble & Wheland J Am Chem Soc 80 5397 1958.] It has also been crystallised from EtOH/H2O. The amide has m 176.5o (from H2O). [Beilstein 9 III 1466, 9 IV 1046.]
